Sand fly fauna (Diptera: Psychodidae: Phlebotominae) in an area of leishmaniasis transmission in the municipality of Rio Branco, state of Acre, Brazil
Parasites & Vectors 2014, 7:360 (7 August 2014)
The sand fly fauna in the urban and peri urban areas of Rio Branco, capital of the State of Acre in the Amazon region of Brazil is very diverse comprising 23 species, as diverse as that in areas of primary forest. Some species, such as Nyssomyia whitmani, Ny. antunesi and Bichromomyia flaviscutellata are known vectors of parasites responsible for cutaneous leishmaniasis in this region.

Distinct variation in vector competence among nine field populations of Aedes aegypti from a Brazilian dengue-endemic risk city
Parasites & Vectors 2014, 7:320 (11 July 2014)
We conclude that Ae. aegypti populations captured during two periods (2009 and 2011) exhibit wide variation in vector competence to transmit dengue viruses in a Brazilian endemic risk city.

Effects of insemination and blood-feeding on locomotor activity of Aedes albopictus and Aedes aegypti (Diptera: Culicidae) females under laboratory conditions
Parasites & Vectors 2014, 7:304 (2 July 2014)
Insemination and blood-feeding effects on the locomotor activity of dengue vectors were evaluated. Data indicate that Ae. albopictus and Ae. aegypti females respond in different ways to physiological status changes. Image: Mosquito inside a glass tube where locomotor activity is recorded.

Effects of temperature and photoperiod on daily activity rhythms of Lutzomyia longipalpis (Diptera: Psychodidae)
Parasites & Vectors 2014, 7:278 (19 June 2014)
Lu. longipalpis is reported to present crepuscular/nocturnal activity in the wild. We individually monitored their locomotor activity under different artificial regimes of temperature and photoperiod. Herein, we display how these environmental factors modulate Lu. longipalpis behaviour. Image: Drosophila DAM5 Activity Monitoring System (Trikinetics Inc., Waltham, MA, USA).

The midgut of Aedes albopictus females expresses active trypsin-like serine peptidases
Parasites & Vectors 2014, 7:253 (30 May 2014)
This paper reports on the characterization of serine peptidases of the midgut from Aedes albopictus females fed on sugar by zymography, in solution assays using fluorescent substrates, two-dimensional electrophoresis (2DE) and tandem mass spectrometry (LC-MS/MS). This analysis revealed a proteolytic profile composed of at least 13 bands ranging from ~25 to 250 kDa, which were identified as trypsin-like serine peptidases by using specific inhibitors of this class of enzymes. Concomitant use of the fluorogenic substrate Z-Phe-Arg-AMC and trypsin-like serine protease inhibitors corroborated the zymographic findings. In addition, proteomic analysis allowed us to confidently assign the expression of two trypsin genes and one chymotrypsin gene to the midgut of this mosquito.
